Caught this on YouTube while fishing around for actual FF SNL footage. Check it out before NBC takes it down:

UPDATE: As noted by a commenter below as well as some of my tweeps on Twitter and the YouTube page from which I pulled the video, the shirtless guy is Jorma Taccone from Lonely Island. For those unfamiliar, Lonely Island has a connection to SNL because they produce most of, if not all of, the digital shorts that air on the show.
